, NITED STATES PATENT OFFICE.- I FREDERICK O. HANS ON, OF UNDERWOOD, NORTH DAKOTA.

BICYCLE-BOAT.

Specification of Letters Patent.

Patented Oct. 16, 1906.

To all whom it may concern.-

Be it known that I, FREDERICK O. HAN- SON, a citizen of the United States, residing at Underwood, in the county of McLean, State of North Dakota, have invented certain new and useful Improvements in Bicycle-Boats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to boats, and more particularly to bicycle-boats, and has for its object to provide a boat operable by footpower, which will include a novel and simple arrangement of parts and which will include steering mechanism constructed and arranged to change the course of the boat with a minimum retardation of its rogress.

Other objects and a vantages will be apparent from-the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of the present boat. Fig. 2 is a top plan view. Fig. 3 is a central longitudinal section on the line 3 3 of Fig. 2. Fig. 4 is an enlarged detail sectional view taken transversely of the boat on the line 4 4 of Fig. 1. Fig. 5 is a detail view of the inner end of the sleeve in section. Fig. 6 is a sectional view of the shaft-bearing.

Referring now to the drawings, the present 7 boat comprises a hull 5, having a pair of spaced brackets 6 therein, in which there is j ournaled a horizontal crank-shaft 7 provided with cranks 8, having pedals 9.

sleeve 10 is mounted in the stern of the boat and receives a ropeller-shaft 11, which is journaled at its orward end in a thrust-bearing 12, secured to the hull and forming a portion of an upwardly-extending seat-supporting frame 13, having a 863.1314 mounted thereu on. The thrustbearing consists of a b ock 15, having a shaft-receiving opening 16, surrounded by a ball-race 1.7. The shaft 11 enters the opening 16 and carries a cone 18, which rests against balls 19, located in the race. A gear 20 is carried by the shaft 11 rearwardly of the block 15, and journaled in this block there is a counter-shaft 21, having a gear 22, meshing with the gear 20, and this shaft 21 extends forwardly and is journaled in a supporting-bracket 23, located between the thrust-bearing and the brackets 6, and forwardly of the bracket 23 the shaft 21 is connected, by means of bevel-gears 24, with the crank-shaft 7. 10 the shaft 21 is threaded, as shown at 25, and engaged with this threaded portion there is an interiorly-threaded disk 26, this disk being provided with a central opening 27, as shown. The disk is recessed, as shown at 28, in its face adjacent to the sleeve 10 and receives in this recess packing 29, the disk being, operable upon the shaft to bring its packing against the end of the sleeve to prevent leakage, and a jam-nut is engaged with the shaft forwardly of the disk to hold the latter against movement.

An outwardly-extending frame 31 is located forwardly of the bracket 6 and has ivoted thereu on a air of hand-bars 32. Fivoted to the ow o the hull outwardly thereof there is a horizontally-disposed triangular steering-head 33, having its apex directed Forwardly of the sleeve forwardly and arranged for horizontal movement, and this steering head is connected, by means of rods 3 1, with the handle-bars 32 for movement when the bars are moved to steer the boat, as will be readily understood.

The shaft 11 carries a propeller-wheel 35 at its rearward end, which extends outwardly of the hull.

What is claimed is A boat comprising a hull, a shaft-sleeve engaged in the stern of the hull, a shaft revolubly engaged in the sleeve and extending into and out of the hull, a propeller-wheel carried by the outer end of the shaft, a packing-receiving disk adjustably mounted upon the shaft, packing in the disk and engaging the inner end of the sleeve, means for holding the disk at different points of its movement upon the shaft, a thrust-bearing in which the shaft is ournaled, a seat mounted above the shaft, a bracket located forwardly of the thrustbearing, a counter-shaft journaled in the thrust-bearing and in the bracket, intermeshing gears carried by the two shafts, brackets located forwardly of the first-named bracket, a crank-shaft journaled in the second-named brackets, cranks carried by the crank-shaft, pedals carried by the cranks, intermeshing- ,bevel-gears carried by the crank-shaft and second-named shaft, an upwardly-extending frame located forwardly of the crank-shaft,

handle-bars mounted in the frame for pivotal I In testimony whereof I affix my signature inovement, 5i horizontally-dispose}? trianguin presence of two witnesses.
